First, in step S10, judging and automatically stop indicating that the value of F is as 1 or is 0, wherein, is that 0 value representation is not yet carried out automatically stopping of driving engine 10, is that 1 value representation has been carried out automatically stopping of driving engine 10.
If judge in step S10 and automatically stop indicating that the value of F is 0, program advances to step S12, determines whether at this stop condition that meets predetermined driving engine 10.In the present embodiment, the stop condition of driving engine 10 is that the logical “and” of following three conditions (A)-(C) is "True": (A) power-transfer clutch is separated, (B) drg just activated (drg is " work "), and (C) moving velocity of vehicle is equal to or less than the first specified speed V1 (for example, 20km/h).Comprise that condition (C) is further to improve fuel efficiency by idle stop control.
In the present embodiment, because driving engine 10 automatically stopped before vehicle stop, what therefore idle stop control (IS (idle stop) being referred to as below in slowing down controls) can lengthen driving engine 10 stops duration automatically, and this causes the raising of the fuel efficiency of driving engine 10.For example can whether be greater than 0 based on brake actuating amount and judge whether drg activated (drg is in " work (ON) " state).Can the output valve based on brake pedal sensor 82 judge brake actuating amount.Can calculate based on the output valve of vehicle-wheel speed sensor 34 moving velocity of vehicle.
If judge and meet stop condition in step S12, program advances to step S14, carries out automatically stopping and will automatically stopping indicating that F is set as 1 of driving engine 10 at this.
If judge in step S10 and automatically stop indicating that the value of F is 1, program advances to step S16, judges at this whether vehicle stops.Execution step S16 is used for determining whether that instruction drg ECU carries out drg supercharging.After automatically stopping driving engine 10, carry out drg supercharging in the idle stop control by slowing down, with the electric power that is supplied to brake actuator 38 by control, brake actuator 38 is activated, thereby within the time period of judging the time that driving engine 10 has been reset, forcibly apply braking force to wheel in the time from judging vehicle stop, prevent from thus unexpectedly making vehicle backward in the time that vehicle is positioned on slope or travel forward.More specifically, in drg supercharging, the electric power that is supplied to brake actuator 38 by control activates brake actuator 38, keeps brake fluid pressure pressure with the hydraulic pressure transducer 46 based in being equal to or greater than authorized pressure.Whether moving velocity that can be based on vehicle is 0 to judge whether vehicle stops, and whether the moving velocity of vehicle is 0 to be that output valve based on vehicle-wheel speed sensor 34 is judged.
If judge vehicle stop (moving velocity is 0) in step 16, program advances to step S18, carries out drg supercharging at this.
On the other hand, if judge that in step 16 vehicle does not stop (moving velocity is not 0) or after step S18, program advances to step S20, determines whether at this condition of resetting that meets predetermined driving engine 10.In the present embodiment, the condition of resetting of driving engine 10 is that the logical “and” of following two conditions (D)-(E) is "True": (D) drg does not activated (drg is " not working "), and (E) power-transfer clutch is separated.
If judging to meet in step S20 resets condition, program advances to step S22, at step S22 place, driving engine 10 is reset, and will automatically stop indicating that F is set as 0.
If judge and do not meet stop condition in step S12, if or in step S20, judge the discontented new starting conditions of lumping weight, or after step S22, program finishes in current circulation.
At each actuator--such as driving circuit, air conditioner system 50 and the car-mounted device of the fuel injection valve 12 of the burning control for driving engine 10, starter 56 may occur various abnormal as ISS-ECU68--.Existing abnormal in the situation that, may there is following trouble.
For example, in the time that driving engine 10 can not be reset due to abnormal in the driving circuit of starter 56, can not guarantee the propulsive effort for vehicle, this may cause after abnormal generation avoids and moving the worry of not carried out rightly.In addition, the negative pressure producing due to the downstream of throttle gate 20 in the time that driving engine 10 can not be reset diminishes, therefore brake servo unit 40 can not assist user to activate brake pedal 42 rightly, and this may cause that braking force is by the worry not being applied to rightly on wheel.Further, because compressor 50a in the time that driving engine 10 can not be reset can not be driven, therefore the defrost function of air conditioner system 50 becomes unavailable.In the time that water smoke appears in windshield, exist user to pass through the confined worry of visuality of windshield.
Especially, in the present embodiment, due to the idle stop control of supporting in deceleration, therefore in the time of vehicle operating, can stop driving engine 10, this may cause such worry: the vehicle operating such as brake actuating will be subject to the adverse influence more of above-mentioned trouble.
For fear of these troubles, suppose, when existing at least one in car-mounted device of judgement when abnormal, to force without any exception to reset driving engine 10 in order to ensure the propulsive effort for vehicle and/or defrost function.But, under such hypothesis, exist user after occurring extremely, may be difficult to take the certain situation of adequate measures: the situation that for example driving engine 10 is reset in the time that user is outside vehicle, more specifically, user opens the car bonnet situation that now driving engine is reset to check driving engine of vehicle in the time that vehicle is static after driving engine 10 stops.
In order to overcome these troubles; in the present embodiment; in the time that driving engine 10 automatically stops; which car-mounted device is execute exception diagnose to judge in exists extremely; in at least one in car-mounted device, exist when abnormal when judging, carry out running state fail-safe operation or quiescence fail-safe operation.Even there is abnormal user at least one in car-mounted device and take adequate measures in this.
Abnormity diagnosis and the fail-safe operation of present embodiment are described with reference to Fig. 4-6 hereinafter.
Fig. 4 illustrates the abnormality diagnostic exemplary process for car-mounted device of passing through ISS-ECU 68 normal execution according to present embodiment.This process repeats with predetermined time interval.
First,, in step S30, judge in ISS-ECU 68 and whether exist extremely.As mentioned above, can whether there is extremely by detecting in ISS-ECU68 with the Engine ECU 64 of ISS-ECU 68 two way communications (the abnormal or exceptional communication that ISS-ECU 68 is own).
In step S32, at least one in decision gate switch 88, fastener switch 90 and car bonnet switch 92, whether exist extremely, these switches are included in occupant and exist in measuring ability.At the abnormity diagnosis that has measuring ability for occupant, for example, voltage is applied to respectively door switch 88, fastener switch 90 and car bonnet switch 92 from constant voltage power suspply (not shown), and " (OFF) do not work " fault or " work (ON) " fault detected during when the foment of the switch based on detecting, judge occupant exist in measuring ability, exist abnormal.
Next, in step S34, judge in Vehicular system and whether exist extremely, wherein Vehicular system comprises various actuators (fuel injection valve 12, light-up plug 14, throttle gate 20 etc.), air conditioner system 50 and brake system and the other system for the burning control of engine system.Mode that can be similar to the abnormity diagnosis that has measuring ability for occupant for the abnormity diagnosis of Vehicular system is carried out.
In next step S36, to judge in start-up function and whether exist extremely, wherein start-up function comprises the element such as driving relay and on-off element, start-up function can be abnormal by the 68b of the abnormity diagnosis portion judgement of ISS-ECU 68.
Subsequently, in step S38, determine whether and detect extremely at least one in above-mentioned steps S30-S36.If judge in step S38 and detect that program advances to step S40, determines whether automatically stopping of executed driving engine 10 at this, automatically stops indicating whether F is 1 extremely at least one in above-mentioned steps S30-S36.
If judge automatically stopping of executed driving engine 10 in step S40, program advances to step S42, detect in this judgement abnormal be whether abnormal in ISS-ECU 68.If judge that in step S42 what detect is abnormal in ISS-ECU 68 extremely, program advances to step S44, replaces ISS-ECU 68 at this by Engine ECU 64.That is, substitute ISS-ECU 68 (main control unit), step subsequently will be carried out in Engine ECU 64 (substituting control unit).
If judge that in step S42 detect abnormal is not abnormal in ISS-ECU 68 or after step S44, program advances to step S46, judges at this whether vehicle stops (static).Execution step S46 is for determining in the case of having abnormal to carry out which fail-safe operation at least one of car-mounted device.That is, at least one in car-mounted device, exist abnormal, in order to ensure the propulsive effort for vehicle, it is desirable resetting rapidly driving engine 10.But for example, in the time that user is not in vehicle, the propulsive effort that is provided for vehicle is undesirable.
In view of the above; in the present embodiment; in step S50, carry out running state fail-safe operation, resetting of driving engine carried out in the judgement at this based on not being static (vehicle moves) for vehicle in step S46 without any exception.When judging that stationary vehicle when (vehicle stop), carries out quiescence fail-safe operation in step S48, wherein whether ride in and in vehicle, carry out resetting of driving engine according to user.Whether user rides in vehicle is not that the moving velocity based on vehicle but other states based on vehicle are judged.
If in step S38, judge at least one in above-mentioned steps S30-S36, not yet detect any abnormal or in step S40, not yet carry out driving engine 10 automatically stop or after step S48 or after step S50, program finishes in current circulation.
Fig. 5 illustrates the diagram of circuit of the running state fail-safe operation of being carried out by ISS-ECU 68 or Engine ECU 64.
First,, in step S60, judge that whether detect abnormal be abnormal in ISS-ECU 68 in above-mentioned steps S30-S36.If judge that in step S60 what detect is abnormal in ISS-ECU 68 extremely in above-mentioned steps S30-S36, program advances to step S62, starts braking non-productive operation apply as the braking force of the function of brake actuating amount Sbrk using complemental brake system 36 at this.Execution step S62 is used for guaranteeing braking force until driving engine 10 is reset.,, in the time that driving engine 10 stops, brake servo unit 40 may become and can not assist rightly user to press down brake pedal 42.Therefore, when vehicle is in the time that the automatic stopping period of driving engine 10 moves, hydraulic pressure raises as the function of brake actuating amount Sbrk by brake actuator 38, and this allows to apply braking force in response to the brake actuating of user's intention to wheel.
In braking non-productive operation, for example, can pre-determine by experiment the mapping of the corresponding relation between feedforward actuating amount and the brake actuating amount Sbrk that limits the brake actuator 38 for keeping the actual brake fluid pressure pressure larger than the brake fluid pressure pressure corresponding to brake actuating amount Sbrk.The electric power that is supplied to brake actuator 38 by controlling according to the feedforward actuating amount that the brake actuating amount Sbrk based on as input value calculates with this mapping activates brake actuator 38.There is no feed forward control, can not obtain via ISS-ECU 68 output valve of hydraulic pressure transducer 46, and the reliability of output valve may reduce.
If judge that in step S60 detect abnormal is not abnormal in ISS-ECU 68 in above-mentioned steps S30-S36, program advances to step S64, considers the negative pressure Pbrk of brake servo unit 40 and starts braking non-productive operation at this.In braking non-productive operation, for example, the electric power that can be supplied to brake actuator 38 by control activates to carry out feed forward control to brake actuator 38, for actual brake fluid pressure pressure is remained to the target brake fluid pressure pressure larger than the brake fluid pressure pressure corresponding to brake actuating amount Sbrk, at this, target brake fluid pressure pressure can increase along with the reduction of the negative pressure Pbrk of brake servo unit 40.In the time that the negative pressure Pbrk of brake servo unit 40b diminishes, also diminish corresponding to the brake actuating amount of user's predetermined downforce, this may make user can not realize the brake actuating that he/her wants.Actual brake fluid pressure pressure is remained to target brake fluid pressure pressure by the deficiency of compensation brake actuating amount.Should be noted that, due to not abnormal in ISS-ECU 68, therefore the hydraulic pressure of brake servo unit 40 and negative pressure Pbrk are available.
Next,, in step S66, judge that whether detect abnormal be abnormal in Vehicular system in above-mentioned steps S30-S36.If judge that in step S66 detect abnormal is not abnormal in Vehicular system in above-mentioned steps S30-S36, program advances to step S68, judges at this whether detect abnormal is the abnormal of start-up function in above-mentioned steps S30-S36.If in step S68, judge in above-mentioned steps S30-S36, detect be the abnormal of start-up function extremely, will in step S70, carry out the setting changing for resetting driving engine 10.At the setting changing for resetting driving engine 10, in the present embodiment, SL1 drives relay 70a and SL2 to drive relay 72a to be substituted by SL1 duplicate relay 70b and SL2 duplicate relay 72b before starter 56 startings.Execution step S70 judges on-off element 74a, 74c for the diagnostic result when based on the 68b of abnormity diagnosis portion, SL1 drives relay 70a and SL2 to drive to exist at least one in relay 72a and like when abnormal, by driving the electrical path of relays to drive starter 56 with can bypass walking around these.
On the other hand, if judge that in step S66 what detect is abnormal in Vehicular system extremely in above-mentioned steps S30-S36, program advances to step S72, judges at least one in light-up plug 14, fuel injection valve 12 and throttle gate 20 whether exist extremely at this.When known engine 10 in advance can not be reset or after driving engine is reset rightly when control engine 10, execution step S72 resets for the pressure of restriction (or forbidding) driving engine 10.
If judge at least one in light-up plug 14, fuel injection valve 12 and throttle gate 20 and exist extremely in step S72, program advances to step S74, judges in DC/DC conv 62 whether exist extremely at this.Execution step S74 for determine whether should limiting engine pressure reset.Need the reasons are as follows of this restriction.
In DC/DC conv 62, exist abnormal in the situation that, can not improve rightly the voltage of battery.When in vehicle operating time, drive starter 56 when resetting driving engine 10, the lower voltage of battery 60, this may cause replacement operation as above.Can not carry out rightly braking non-productive operation by brake actuator 38, power steering system 52 can not assist user to handle steering handwheel rightly.Therefore, determine whether should limiting engine reset.
If judge in step S74 in DC/DC conv 62 and exist extremely, program advances to step S76, whether the logical "or" of judging following condition (F)-(G) at this is "True": (F) the moving velocity V of vehicle (is for example equal to or less than the second specified speed V2,7km/h), the second specified speed V2 is less than the first specified speed V1 and is greater than 0, and (G) drg does not activated (drg is " not working ").Execution step S76, even for judging at DC/DC conv 62 have abnormal in the situation that whether can remove the restriction that the pressure of driving engine is reset.This operation is based on following hypothesis, and, in the time that the known user of the fact low or that drg does not activated of the moving velocity V from vehicle is intended to make vehicle movement, vehicle operating is by the less impact that is subject to replacement operation.
In the time being transitioned into step S78, what judgement needn't limiting engine resets.The judgement of the user that the fact based on by vehicle not being static (vehicle moves) obtains in vehicle carried out the pressure of driving engine and reset.
Subsequently, in step S80, judge whether driving engine 10 is reset.Whether the engine speed that for example, can derive based on output valve by crank angle sensor 18 is equal to or greater than the predetermined speed that driving engine 10 can keep on the go is certainly judged whether driving engine 10 is reset.
If judge that in step S80 driving engine 10 is reset, program advances to step S82, stops braking non-productive operation at this.Step S82 considers to be reset therefore brake servo unit 40 and become the fact can additional brake activating due to driving engine 10.
On the other hand, in step S80, judge that driving engine 10 is not yet reset, suppose that driving engine 10 resets failure.In next step S84, will produce notice for pointing out user to take suitable avoidance action such as avoiding operation in the situation that noting brake actuating.In service in avoidance, for example, after occurring extremely in car-mounted device, user transfers to vehicle side strip from moving traffic lane.,, in the time that driving engine 10 stops, brake servo unit 40 may become and can not assist rightly user to activate brake pedal 42.For example, in the time of user's pump pressure drg, can not guarantee the negative pressure of brake servo unit 40, this causes following situation: braking force can not be applied on wheel rightly.Therefore, above-mentioned notice can point out user to take adequate measures.In this notice, for example, be presented at visual information on the telltale of navigationsystem 54 or visually or acoustically indicate user vehicle to be sailed to safer place the pump pressure drg not in the situation that from the acoustic information of navigationsystem 54, on curb.
If judge in step S72 and there is no logical "or" abnormal or decision condition (F)-(G) in step S76 at least one in light-up plug 14, fuel injection valve 12 and throttle gate 20 as " vacation " or after step S82 or after step S84, program finishes in current circulation.Step S60, S62 and step S78-S84 subsequently carry out by Engine ECU 64.Other steps are carried out by ISS-ECU 68.
Fig. 6 illustrates the diagram of circuit of the quiescence fail-safe operation of being carried out by ISS-ECU 68 or Engine ECU 64.
First,, in step S90, judge that whether detect abnormal be abnormal in start-up function in above-mentioned steps S30-S36.If judge that in step S90 what detect is abnormal in start-up function extremely in above-mentioned steps S30-S36, program advances to step S92, judges at this whether starter 56 is unexpectedly driven.Execution step S90 is for checking abnormal appearance, although make some thing for having triggered starter 56 the start request that starter 56 is started, starter 56 be driven in the case of lacking.
If judge that in step S92 starter 56 is unexpectedly driven, program advances to step S94, at this separating speed changer.Execution step S94 activates gear shifting actuator 24c for the electric power that is supplied to gear shifting actuator 24c by control, to interrupt the moment of torsion transmission between bent axle 16 and drive wheel 32, avoids the power of vehicle to move thus in the time that starter 56 is unexpectedly driven.
If if judge that in step S90 detect abnormal is not abnormal in start-up function or judge that in step S92 starter 56 is not yet unexpectedly driven in above-mentioned steps S30-S36, judge in step S96-S104 whether user rides in vehicle.; if judge that in step S90 detect in above-mentioned steps S30-S36 abnormal is not abnormal in start-up function, in step S96, S98, judge that whether detect abnormal be that occupant exists abnormal in the abnormal or Vehicular system in measuring ability in above-mentioned steps S30-S36.
If judge that in step S96, S98 detect abnormal is not that occupant exists abnormal in measuring ability in above-mentioned steps S30-S36, but abnormal in Vehicular system, program advances to step S100, whether the logical “and” of judging following condition (H)-(I) at this is "True": (H) user just rides in vehicle, and (I) the moment of torsion transmission between bent axle 16 and drive wheel 32 is interrupted.Execution step S100 is used for confirming that user is just riding in vehicle, then in the time of abnormal in the abnormal or Vehicular system existing in start-up function, resets forcibly driving engine.Whether user rides in vehicle can the logical “and” based on following condition (J)-(L) be that "True" is judged: (J) the output valve decision gate based on door switch 88 is closed, (K) output valve based on fastener switch 90 judges that user has worn safety strap, and (L) output valve based on car bonnet switch 92 judges that car bonnet is closed.If logical “and” is "True", can think that user is just riding in vehicle.
Above-mentioned condition (I) is the condition for avoid to stall and unexpectedly making vehicle movement in the time that driving engine 10 is reset.,, in the time that the moment of torsion of driving engine 10 is being passed to drive wheel 32 from bent axle 16 in the time that driving engine 10 is reset, may occur to stall and the motion unintentionally of vehicle because the propulsive effort of starter 56 is used to power operation.Therefore, above-mentioned condition (I) causes the generation of the unexpected motion that prevents engine off and vehicle.Whether the moment of torsion of driving engine is being passed can the logical "or" based on following condition (M)-(N) be "True" state is judged: (M) shift position of gearshift is positioned at neutral gear, and (N) power-transfer clutch is separated.
If judge that in step S98 detect abnormal is not abnormal in Vehicular system in above-mentioned steps S30-S36, judge that what in above-mentioned steps S30-S36, detect is abnormal in ISS-ECU 68 extremely.In step S102, whether the logical “and” of judging following condition (O)-(P) is "True": (O) accelerator is activated by user, and (P) the moment of torsion transmission between bent axle 16 and drive wheel 32 is interrupted.Execution step S102 is just riding in vehicle when ISS-ECU 68 exists user when abnormal for confirming, then resets forcibly driving engine.
Condition (O) is for judging whether user wants to reset the condition of driving engine 10.That is, abnormal owing to existing in ISS-ECU 68, the reliability of the output of door switch 88, fastener switch 90 and car bonnet switch 92 reduces, and this may make to be difficult to export and judge exactly whether user rides in vehicle based on these.In the time that accelerator activated, can think that user is just riding in vehicle and wanting to reset driving engine 10.Therefore, driving engine can be reset.Whether output valve that for example, can be based on taking accelerator pedal sensors 80 is greater than 0 judgement as basis to accelerator actuating amount is judged whether accelerator activated.
If judge that in step S96 what detect is that occupant exists abnormal in measuring ability extremely in above-mentioned steps S30-S36, program advances to step S104, whether the logical “and” of judging following condition (Q)-(R) at this is "True": (Q) power-transfer clutch activated, and (R) the moment of torsion transmission between bent axle 16 and drive wheel 32 is interrupted.Execution step S104 determines whether the restriction of resetting of releasing to driving engine when abnormal for exist measuring ability to exist as occupant.Condition (Q) is for confirming that user is just riding in the condition in vehicle.,, even when power-transfer clutch is in the time that occupant exists measuring ability to exist also to activated abnormal in the situation that, user may be in vehicle.Can whether be greater than 0% judgement based on clutch actuation amount and judge whether power-transfer clutch activated.Condition (R) is for avoiding to stall and the condition of analogue.
If the logical “and” of decision condition in step S100 (H)-(I) is "True", if or the logical “and” of decision condition (O)-(P) is "True" in step S102, or the logical “and” of decision condition in step S104 (Q)-(R) is "True", program advances to step S106, resets forcibly driving engine at this.In next step S108, judge whether driving engine 10 is reset.If judge that driving engine 10 is reset, program advances to step S110, stops drg supercharging at this.In the time carrying out braking non-productive operation, also stop braking non-productive operation.
If the logical “and” of decision condition in step S102 (O)-(P) is " vacation ", if or the logical “and” of decision condition (Q)-(R) is " vacation " in step S104, if or judge that in step S108 resetting of driving engine 10 is failed, program advances to step S112, produces notice be used for pointing out user to reset driving engine 10 joined speed variator by rotating ignition lock 58 at this.If judge the failure of resetting of driving engine 10, produce notice, this can alleviate cause to user while continuing to stop after driving engine 10 is being reset driving engine 10 failures forcibly uncomfortable.In addition, if the logical “and” of decision condition in step S102 (O)-(P) be " vacation " or in step S104 the logical “and” of decision condition (Q)-(R) be " vacation ", produce notice, this makes user can in the time not wanting to reset driving engine 10 or in the time that the propulsive effort of starter 56 may be used to the power operation of vehicle, take adequate measures.
In change-speed box engages, the electric power that is supplied to gear shifting actuator 24c by control activates gear shifting actuator 24c, and the moment of torsion of driving engine is transmitted between bent axle 16 and drive wheel 32.Engage the unexpected motion backward or forward for prevent vehicle in the time that vehicle stop can not be reset on the slope time when driving engine 10 even if carry out change-speed box.More specifically, the electric power that is supplied to gear shifting actuator 24c by control activates gear shifting actuator 24c, make the transmission ratio of MT 24 in the time that vehicle stop is on up slope in D Drive scope (first grade), in the time that vehicle stop is on descending slope, the transmission ratio of MT 24 is in reverse gear scope (reverse gear).
In above-mentioned configuration, if the logical “and” of decision condition in step S102 (O)-(P) is " vacation ", if or the logical “and” of decision condition (Q)-(R) is " vacation " in step S104, if or failure (driving engine is reset failed), execution notice are reset in the pressure of judging driving engine 10 in step S108.Alternately, in ISS-ECU 68, exist when abnormal when judging by Engine ECU 64, or in start-up function, exist when abnormal when judging by ISS-ECU 68, can carry out notice, this makes user can be pointed out earlier to reset driving engine by rotating ignition lock 58.In addition, after notice, can stop braking supercharging and braking non-productive operation when judging by rotating when ignition lock 58 is reset driving engine 10, wherein, judge in ISS-ECU 68 and exist the abnormal time to reset the time consistency of failure with judging driving engine.
If the logical “and” of decision condition in step S100 (H)-(I) is " vacation ", or after step S94, or after step S110, or after step S112, program finishes in current circulation.
Braking supercharging will continue, until judge that driving engine 10 is reset in quiescence fail-safe operation.This makes during starts to prevent that for the upward slope/descending at vehicle downwards/proal defencive function (slope maintenance function) can be kept.
After judging in running state fail-safe operation or quiescence fail-safe operation that driving engine 10 has been reset, need driving engine 10 can not for example automatically stop until vehicle is repaired at repair plant.
Now by some advantages in explanation present embodiment.
(1) exist while existing abnormal (or having occurred abnormal) and vehicle moving at least one in measuring ability, Vehicular system and start-up function ISS-ECU 68, occupant when judging at the automatic stopping period of driving engine 10, reset forcibly driving engine 10.This allows to guarantee the propulsive effort of vehicle and therefore allow user to take adequate measures existing abnormal in the situation that, such as avoiding operation.
(2) judge in DC/DC conv 62 when the automatic stopping period of driving engine in the situation that vehicle moves 10 while there is extremely (having occurred abnormal), the pressure of limiting engine 10 is reset, and this can prevent from rightly braking non-productive operation or similar operations operates and is performed owing to resetting.
In addition, in the time judging that the moving velocity V of vehicle is less than the second specified speed V2 or drg and does not activated, remove the restriction that the pressure of driving engine is reset, this makes it possible to guarantee as early as possible the propulsive effort of vehicle.
(3), in the time existing extremely in the automatic stopping period of driving engine 10 is judged ISS-ECU 68 and vehicle is moving, subsequent operation substitutes ISS-ECU 68 by Engine ECU 64 and carries out.Even if this also can be reset starter 56 in the situation that there is ISS-ECU 68, allow thus driving engine 10 to be reset.
(4) when judging that SL1 in the driving circuit of starter 56 drives relay 70a and/or SL2 to drive to exist in relay 72a when abnormal, resets driving engine forcibly by SL1 duplicate relay 70b and/or SL2 duplicate relay 72b.Also can be reset even if this exists abnormal in the situation that starter 56 in driving circuit or like, allow thus driving engine 10 to be reset.
(5) at least one in Vehicular system and start-up function, there is abnormal and stationary vehicle and the output valve based on fastener switch 90 and while judging that user is just riding in vehicle, reset forcibly driving engine when judging at the automatic stopping period of driving engine 10.This allows user to take subsequently adequate measures.
(6) when judging at the automatic stopping period of driving engine 10 that starter 56 has unexpectedly been driven and when stationary vehicle, the electric power that is supplied to gear shifting actuator 24c by control activates gear shifting actuator 24c, and the moment of torsion transmission between bent axle 16 and drive wheel 32 is interrupted.This can prevent that the propulsive effort of starter 56 is used to the power operation of vehicle rightly.
(7) when there is abnormal and stationary vehicle in the automatic stopping period of driving engine 10 is judged ISS-ECU 68 time, the pressure of limiting engine is reset.This allows user to take subsequently adequate measures.
In above-mentioned situation, in the time judging that accelerator activated, remove the restriction that the pressure of driving engine is reset.This makes it possible to guarantee as soon as possible the propulsive effort of vehicle.
(8) in the time judging that the pressure of driving engine 10 is reset failure and vehicle and moved, provide notice to note the actuating of brake actuating element with prompting user to user.This allows user to take adequate measures, such as avoiding operation.
(9), in the time judging that failure and stationary vehicle are reset in the pressure of driving engine 10, provide notice to carry out fire an engine 10 with prompting user by rotating ignition lock 58 to user.This allows user's fire an engine 10 and do not cause uncomfortable to user rightly.
(10) when there is abnormal and stationary vehicle in the automatic stopping period judgement of driving engine 10 occupant exists measuring ability time, if at least one in judgement clutch equipment 22 and MT 24 interrupted the moment of torsion transmission between bent axle 16 and drive wheel 32, remove the restriction that the pressure of driving engine 10 is reset.This make to prevent due to the propulsive effort of driving engine 10 in the time resetting driving engine 10, be used to that power operation causes to stall and the motion that meets accident of vehicle.
(11) carry out braking supercharging with driving engine 10 the stationary vehicle in the situation that automatically stopping period apply forcibly braking force to wheel, and till lasting till and judging that driving engine 10 has been reset.This can prevent the unexpected motion backward or forward of vehicle in the time that vehicle is positioned on slope.
Subsequently, in the time judging that driving engine 10 has been reset, stop braking supercharging.This allows braking supercharging to stop at reasonable time.
